A zymogen is the inactive precursor of an enzyme. The molecule is composed of amino acids strung together into a peptide. When the zymogen is in the presence of an enzyme specifically designed to breakdown peptides, called a protease, some of the amino acids are removed.This cleavage renders the zymogen a functional enzyme by changing the shape of the peptide and forming the active site where enzymatic action will occur.hen the zymogen is in the presence of an enzyme specifically designed to breakdown peptides, called a protease, some of the amino acids are removed.
